Transcript PNF Stretching

Sports Med 2
 Proprioceptive
 Neuromuscular
 Facilitation
 First
used by physical therapists for treating
patients who had various types of
neuromuscular paralysis
• Now used as a stretching technique to increase
flexibility
 Stretching
techniques that involve
combinations of alternating contractions and
stretches
 Used in rehabilitation to facilitate strength
and increase ROM
ADVANTAGES


Increase muscular
flexibility
Increase ROM
DISADVANTAGES


Exercises require a partner
Exercises require expertise
•PNF involves 3 types of Movements
•Flexion/Extension
•Abduction/Adduction
•Internal/External Rotation
 Passive
• The degree to which a joint may be passively
moved to the endpoints in the ROM
• No muscular contraction is involved
 Active
• The degree to which a joint can be moved by a
muscle contraction
 Isometric
• Means to contract a muscle statically without
changing its length
• This contraction is referred to has “hold”
 Concentric
• The muscle shortens while contracting against
resistance
• This contraction is referred to as “contract”
 Passive
stretches
• Referred to as “relax”

Hold-relax
• Passive stretch – for 10 sec.
• Athlete is instructed to “hold and not let leg move” for 6 seconds
 Athlete resists movement which creates isometric contraction
• Athlete relaxes
• Passive stretch held for 10 sec.
• Repeat 3 times


Contract-relax
•
•
•
•
•
Passive stretch –hold for 10 sec
Athlete isotonically pushes against resistance from partner-6 sec
Athlete relaxes
Passive stretch applied and held for 10 sec.
Repeat 3 times
•
•
•
•
Athlete moves body part to point of resistance and is told to “hold”
Muscles are isometrically resisted by partner for 6 sec.
Athlete relaxesAthlete moves body part into farther ROM- stretch 10 secs
hold-relax- with contraction
